The article missed pointing out a very important detail about H-1B1 visa (for Chile and Singapore): unlike the dual intent H-1B visa, the H-1B1 is a non-immigrant visa. This means that you must establish the non-immigrant intent to get it. It also means that, should you happen to change your mind after some time, you would have to switch to H-1B visa before trying for the green card.

Also, speaking from the personal experience, the fact that the H-4 visa doesn't allow your spouse to work deserves more emphasis. If there's anything that might drive me and my family back to Chile, it's the H-4 visa.
